  1. 1. Evaluating the quality of ultrasonic signals using machine learning : A comparative study on binary classification methods applied on ultrasonic chirp signals

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Fabian Revilla; [2023]
    Keywords : mechatronics; machine learning; ultrasonic; bolt-tightening; nutrunner; clamp force control; elongation control; pre-load control; cross-correlation; mekatronik; maskininlärning; ultraljud; skruvdragare; klämkraft; klämkraftsåtdragning; klämkraftsreglering; korskorrelation;

    Abstract : Advanced bolt-tightening tools such as automatic nutrunners are commonly used in industrial factories to streamline the assembly process. In safety-critical systems, it is crucialto control the tightening process. READ MORE

  3. 2. Classification of ultrasonic signals using machine learning to identify optimal frequency for elongation control : Threaded fastening tools

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Mazen Bahy; [2022]
    Keywords : Machine Learning; Convolutions Neural Network CNN ; Barker signals; Ultrasonic sensors; Clamp-force; Threaded fastening assembly; Maskininlärning; konvolutionellt neuralt nätverk; Barker-signaler; Ultraljudssensorer; klämkraft; Åtdragningsmontering;

    Abstract : Studying the preload in a screw joint has been the focus of today’s industry. The manufacturer reflects that demand by investigating different opportunities and techniques to develop this area. There are four different ways of controlling the tightening of bolts and joints to achieve the required clamp force that can hold for a specific preload. READ MORE

  4. 3. Design of a Tribometer to Study Friction inThreaded Fastener Interfaces

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Zhan-Jun Lin; [2020]
    Keywords : tribometer; friction coefficient; tightening; pin-on-disc; tribometer; friktionskoefficient; åtdragning av skruvförband; pin-on-disc;

    Abstract : Bolts and nuts are one of most common joining methods since they are simple and low-cost to connect parts. Appropriate clamp force from bolted joint remains resultant joints secured, but higher/lower preload on bolted joint increases risk of the failure of mechanism. READ MORE

  5. 4. Characterization of machine tool components for drilling operations with intergrated damping system

    University essay from KTH/Industriell produktion

    Author : Ho Duong Dong; [2011]
    Keywords : ;

    Abstract : In recent years the control of tool vibration has emerged as the critical area of scientific development. This is because tool vibration creates sound-noise and unwanted quality surface. Mathematically, the observed tool vibration is a ratio of the force acting on the tool to its dynamic stiffness.
